Frequently asked questions
- Is it really free and unlimited?
- Yes. Everything runs in your browser, so there are no server costs and no limits.
- Do my images get uploaded anywhere?
- Never. The compression happens entirely on your device — your photos are never sent to a server.
- How do you hit an exact KB size?
- The tool searches for the highest image quality whose file size still fits under your target, then downscales if needed.
